Your "qualified" electrical engineer may have scraped a pass in an exam a couple of decades ago but I can think of some that I would not let anywhere near my own fuse box. I once had to administer hot sweet tea to an ashen grey electrocuted US service engineer who forgot that UK mains was 240v and tested for live with moist fingers! Another plunged the entire site into darkness by dropping a spanner into the wrong place! peer-reviewed journals, those who hold impressive academic posts... are, at least in the field of their specialty, a better foundation to trust in to build your own self-consistent edifice of knowledge... You are sailing dangerously close to an appeal to authority here. You can have brilliant individuals with the highest academic credentials who cannot teach students to save their lives. And they do have the unfortunate effect of sounding exactly like the handwaving loons since no one at their lectures can follow their reasoning. Relativity teaching in electronics engineering courses often seems to follow this model. I do agree in principle at least that it is better to listen to someone of the stature of Prof Sir Martin Rees, Astronomer Royal and Chair of the Royal Society who is an excellent communicator of modern science than any of the nutters and netkooks listed below. than self-appointed "experts" who proclaim that there is a BIG CONSPIRACY to hide the fact that dinosaurs walked the Earth along with men, that flying saucers are visiting us each day, and so on and so forth. Do you truly feel that I am giving unsound advice in so recommending? I know I have no hesitation in choosing Newton, Einstein, and Darwin over Gerard Kelleher, Brad Guth, and Ed Conrad. Of course not. The last 3 netloons are all in my kill file although EdConman keeps morphing to evade it. Oriel36 only got through yesterday because I was testing an unfiltered newserver - his babble is predictable and easily simulated by a Shannon entropy based algorithm. But you are on shakier ground with the electronics engineer Ivor Catt (MA Cantab) who had some very strange ideas about electricity and relativity and ranted about them incessantly in the pages of the UK electronics magazine Wireless World (aided and abetted by the then editor who also had a bee in his bonnet about relativity). Wiki has a bit on him: http://en.wikipedia.org/wiki/Ivor_Catt Some of his ideas on wafer scale integration were excellent. Of course, having passed first-year calculus and the like makes it possible for me to see that, no, I have not been brainwashed, but have in my hands truth I can understand, verify, and work with. If scientific orthodoxy were nothing more than faith in the most impressive and conventional authorities, there would be nothing to choose between the orthodox and the rebels. You have to keep that distinction clear. And it gets more than a bit hazy in areas of bleeding edge research in string theory and cosmology. It is precisely the ability to confirm science by experiment that distinguishes truth from dogma, the expert from the charlatan, and progress from ignorance. I don't approve of the way you want to claim truth vs dogma. Formal proof of correctness is only possible in mathematics not in science. Science by its very nature gives us a working description that matches reality - it might or might not be correct, but as yet noone has found an experiment that falsifies it. The opposite of ignorance is knowledge. Regards, Martin Brown |

The opposite of ignorance is knowledge. That was another issue that I didn't want to touch on due to lack of space. Yes, Einstein showed us that Newton didn't give us absolute Truth, and so it may well turn out that Einstein didn't give us absolute Truth either... if you don't count quantum mechanics as having *already* proven that. And it's in the very early days for string theory. Bringing in the strong and weak nuclear forces seems to have solved the renormalization problems of Kaluza-Klein, but, yes, we're still a ways off from knowing if it's more than pretty mathematics. My point is not to say that authority makes truth. But that if you don't know the science yourself, it's just common sense to prefer authorities who appear to be widely respected - at least if that respect appears to have been obtained honestly, that is, without coercion - to the "nutters". The trouble is that people like Velikovsky and von Daniken can spin pretty impressive and convincing arguments to a naive layperson. To a person otherwise helpless against them, while authority may be a weak reed, it is better than having no defense at all. John Savard |

In John D. Clark's "Ignition!" he mentions that at one point in the late 1950s a group of Russian rocket engineers published details in the open scientific press of a rocket fuel/oxidiser combo which was superior to the state of the art known to the US defence field. The Russians were apparently under the impression the information they had made public was actually widely known. It caused some head-scratching in the US, in part because the thinking went that if the Russians thought this advanced rocket fuel/oxidiser combination was common knowledge, just how advanced was their secret stuff? We did the same thing in reverse - Adm Rickover openly published much information on our [Naval] nuclear power program, until he toured the [then] new Soviet icebreaker Lenin. Seeing how far behind they were, and much of what he thought of as obvious actually wasn't, he returned home and promptly classified great swathes of basic technology and engineering. OTOH it was widely believed in the Fleet that we intentionally leaked details of our SLBM fire and launch control systems (which had standby and training modes in addition to the launch modes) in hope the Soviets would adopt them and replace their systems which only had 'off' and 'launch' modes.

My father worked on the Manhattan Project as a very junior scientist, and he never believed all the paranoia and propaganda about "Soviet atom spies," to the point he wasn't entirely sure there WERE any. He said that once you knew a bomb COULD be built, actually doing it just wasn't that big a challenge, and certainly wasn't too much for the Soviets to figure out. They weren't stupid. (Yes, I know the Soviets really did steal the information, but when Dad was talking about this forty-five years ago that wasn't yet established beyond all reasonable doubt. American propaganda was usually less blatantly false than what the other side produced, but it still wasn't very trustworthy.) Your father probably didn't realize what many people still don't realize today - that even though the *science* of a bomb is fairly straightforward, the *engineering* is anything but. The two are often confused even though they are radically different things. D. -- Touch-twice life. Eat. Drink.

How then are we constantly bombarded with "scientific" studies that "prove" that butter, red wine, meat, eggs, bread, you-name-it, is bad for you, good for you, bad for you, etc.? Or that the world is warming, cooling, changing? Could it not be a question of "he who pays the piper" and that qualified scientists are playing the tune requested in many cases without reporting on the rest of the symphony? I might trust the scientist, but I don't trust the person who is paying him or her, and even university research is not above suspicion. -- Rob Bannister |
